I Have Been On Lexapro 10mg Now For 3 Months.

I have been on lexapro 10mg now for 3 months. Before Lexapro I was on Zoloft 75 mg which was working great, until it seemed to stop working for my anxiety. I am experiencing many side effects with the lexapro such as : increased depression, no appetite, and headaches. My MD was wanting to increase the dose, but I am thinking this drug is not for me. Any recommendations on what my next steps should be?
